It happened at the Down House restaurant in Houston.
After the woman dined there she went on Twitter and called the bartender a "twerp."
On her Twitter page she admits she is opinionated and feisty.
However, when she went back to the restaurant, the manager told her to leave.
"If you go to someone's house and start calling them names, I wouldn't really expect to stay too much longer after that," restaurant owner Chris Cusack said.
Others are tweeting about what happened, one person saying, "The Down House owes her a big apology." On the other hand, it has brought the restaurant a little fame.
